I change the $3 PCV valve every other oil change and just buy a handful everytime I get oil filters. Since installing Fumoto valves on both VX's the oil change routine is tool-less and quick.

As for DeLoreans: We got one once from a GSA auction and it was quite nice, especially for $5K with no issues other than no keys and a stolen radio. Except it knocked me nearly unconcious twice while detailing it with the doors open. Gullwings are hazardous when you're tall!
